Take extras but be ready for anything. When broke both rear leaf springs on our 5ver on the intertstate in Edmundton BC. Luckly they have a leaf spring factory there and we were back on the road in less than 24 hours. I had to wait for WalMart to open in the morning to buy another jack and jack stands to change them out while parked in a gas station. Alaska was great but the back country in BC was better. The Provinscial Parks are inexpensive, a few dollars a night and some provide fire wood. Every little town has a city park and they have free dump stations and fresh water in the park. I could be a Canadian easy. Beautiful Country.
Have a great trip and while in BC if your navagator (the DW) says to you that there are a lot of towns on the map with the same name "FERRY", there not towns. There are Ferry's to get you across the lakes and most are free.
